检查在Rails控制器上的ruby中收到的表单数据

Question

I want to check the form data received from the form in ruby on rails controller.

I tried this but nothing is shown:

@user.to_yaml

where @user is the form name( <%=form_for @user )

Answer 1

the data sent by a form is stored in the params hash (see this question for more information).

also, in development, just put a raise in your controller action to show an error page with all request parameters displayed.

Answer 2

The above answer is correct. but will like to change something

all the details are stored in params only

and it will be better to show those in flash by doing flash.notice = params

as it will not effect the working of app

Answer 3

为什么不在控制台上签出服务器日志或使用调试器gem来跟踪请求所沿的参数和文件...
